Problems solved by technology

[0002] At present, some mechanical equipment needs engine oil to lubricate the bearings. Due to the compact structure, it is usually sealed with a skeleton oil seal, and the skeleton oil seal is a seal that is in contact with the rotating shaft. When the oil seal is worn, the oil will leak out, causing damage to the machine and pollute the environment, and at the same time, the contact between the skeleton oil seal and the rotating shaft will also generate frictional resistance to the shaft

Abstract

The invention relates to a mechanical sealed-in unit. It comprises: an oil chamber end covering, a sloping oils gear ring and a grease ring. On the bottom of the oil chamber provided oil return holes, the out covering is fixed on the oil chamber covering and the inner hole forms a labyrinth seal with the sloping oil gear ring; on the outside of the sloping oil gear ring provided a grease ring and a ring oil slot is arranged on the inner hole wall of the out end covering, the ring oil slot is connected with oil return hole on the oil chamber covering.

Description

Technical field: [0001] The invention relates to a mechanical seal device for shafts of ordinary mechanical equipment, in particular to a mechanical seal device for extending shafts without pressure in an oil chamber. Background technique: [0002] At present, some mechanical equipment needs engine oil to lubricate the bearings. Due to the compact structure, it is usually sealed with a skeleton oil seal, and the skeleton oil seal is a seal in contact with the rotating shaft. When the oil seal is worn, the oil will leak out, causing machine damage and It will pollute the environment, and at the same time, the contact between the skeleton oil seal and the rotating shaft will also generate frictional resistance to the shaft. Invention content: [0003] The purpose of the present invention is to provide a mechanical sealing device with good sealing effect. [0004] The solution of the present invention is as follows: it contains an oil chamber end cover, an inclined plane oil...
